Owing to intricate interdependency and information feedback
among tasks, the concurrent design process probably cannot converge to the correct solution when
there are wrong integration and improper interaction between activities. Therefore research on
concurrent design process optimization is necessary. In the paper, a novel methodology is
proposed to analyze and optimize the concurrent engineering process scientifically. Based on
design structure matrix and graph theory, coupled task recognition and design task level plotting
are performed for the concurrent design process of aluminum profile extrusion product
development. Three factors are used to describe the coupling property of activity, namely
sensitivity, complexity and affection factors, which provide the basis to analyze development
process quantitatively. And an optimism algorithm is presented to define the initial iteration
order of coupled task set. Finally a rational and efficient concurrent design process model is
constructed, which can make aluminum profile product development faster, with lower costs and
higher quality. The methodology proposed is also applicable to other concurrent engineering
fields.
